We ordered a dozen of these for an annual event.  Basically, the backs were not sturdy enough to keep the mirror in place and had to be reinforced, particularly if we wanted to be able to reuse them.  The aesthetic is nice, and overall, it worked, but it required a fair amount of additional labor on our end, which impacted the overall cost to us.

We did receive one badly damaged in shipping, but Wayfair quickly replaced it.
